[QUOTE="SSG Graybush, post: 2392887, member: 115190"] You are wrong about that, imo. 6 thou nodes are the norm. Some bigger, some smaller. Dont use the smaller. And you may jump over using 20-30 thou increments. I test at 3 thou increments and find both ends and load the middle. Because being on the edge of the node leads to inconsistency from things like environment and variants in charge weight. Falling out of the node causes flyers/larger groups. I jumped over nodes before so I do 3 thou increments and with Bergers I test 55 to 70 thou jump 1st. Then depending on a bullets variance( not Bergers so much) in bbto/ojive start at 5 or 10 thou off lands. And the variance in bbto/cbto can be overcome to get consistent jump by short seating bullets, measure, separate into lots by cbto, and seat the rest of the way. I get a variance < 2 thou this way. A good micrometer seating die helps a lot in this. Redding with the vld stem works well for me. The Barnes 112 gr MB's shoot great but their bbto/ojive variance can cause a variance up to 8 thou in cbto, that alone can/does cause flyers. The 105/109 gr Bergers were out of stock so I had to try the 112 gr MB's for my 6 XC. I had to do this to get to .4ish moa, and a ES of 15. Sub half and a ES of 15 or less is my goal for any LR shooting rifle. [/QUOTE]
